Sony Trinitron Model No. Kv-27TS36 made in January...

Question

Screen doesn't work. It goes on and all you can hear is sound, no image. Apparently the Timer/Stand by light is flashing every second or so. It represents some kind of failure but I dont remember which one. Any ideas of what it is?Would it cost me more to repair it than to buy a new one? (how much would it be, more or less?)Thanks, Sincerely Fernando
